I also have the same problem (rescued a chicken who doesn't like the coop),except she was roosting on my deck. And soon they all started doing it. Our trees are too big for them to reach the lowest branches. I have been battling this for 2 months, and lock-down did not work for me. I tried throwing them off the deck, corraling them with a stick, carrying them, etc. Nothing worked. But I think I might have found the cause in my case.
I think they are roosting on my deck because of all the lights, it stays lighted all night long. So last night I turned off all of the lights about a half-hour before dusk, and only had one hen roost on the deck, all others went to the coop.
So in my case, I think I just need to turn off the lights in the back yard.
